7 - Quiz #3 test questions
and answers
detection of rough areas on tooth surfaces
the modified pen grasp allows:
True
True/False: the modified pen grasp lessens musculoskeletal stress
handle
where you hold the instrument
shank
rod-shaped length of metal located between the handle and the working
end; generally circular, smooth, and much smaller in diameter.
working end
the part that does the work of the instrument
to hold the instrument on the handle
what is the function of the index finger & thumb?
helps to guide the working-end; feels vibrations transmitted from the
working-end to the shank
what is the function of the middle finger?
stabilizes and supports the hand for control and strength; advances ahead
of other fingers in the grasp
what is the function of the ring finger?
has no function in the grasp
what is the function of the pinky?
vary
the exact position of the fingers in the modified pen grasp will ________
slightly among clinicians
loose fitting across the palm and wrist area
gloves should be:
, hypermobility
joints that easily move beyond the normal range expected
"double-jointed" or joint laxity
hypermobility is also described as:
bending thumb and index finger in grasp
the clinician counteracts joint hyperextension by:
proprioception
a person's ability to sense their body, its position and movement through
space
reduced
studies show that individuals with joint hypermobility have ______________
proprioceptive sensitivity in joints of the hands
thumb and index finger collapsing forward
an individual with hypermobility must learn to grasp the instrument
without the joint of the:
force
DO NOT grasp the instrument with too much __________
silipos sleeve
a _______ ________ can assist grasping the instrument handle
long fingernails
what can interfere with a correct grasp and finger rest technique?
dental mirror
used to view tooth surfaces that cannot be seen using direct vision
front surface
the reflecting surface is on the front surface of the glass; produces a clear
image with no distortion
concave
the reflecting surface is on the front surface of the mirror lens; produces a
magnified image
plane (flat surface)
the reflecting surface is on the back surface of the mirror lens; produces a
double image
